(sshd) Unable to forward TCP port
Hi! I'm trying to forward a TCP port from localhost of the remote server to the local machine using SSH. After the SSH connection is established I try to use the forwarded port but the tunnel is not working and a get the following error in /var/adm/messages : Oct 6 13:27:12 hisoft-oisrvh01 sshd1543: [ID 800047 auth.error] error: setsockopt TCP_NODELAY: Invalid argument
Nevertheless the telnet shows that the tunneling connection is established - I can put lines as many as I want but respondless.. And I see no warnings in terminal. X11 connections work Ok - I can use GUI-applications remotely (with -X).
So I put the "AllowTcpForwarding yes" option into sshd_config and restarted sshd but useless.
I don't know if it is a new security feature or a bug but the ssh-tunneling is a main thing I use for my work..
Please help me to resolve the problem - it's very important at least for my job...
